IMPROVEMENT IN CHURNS.

Specification forming part of Letters Patent No. 187,525, dated February20, 1877; application filed December 23, 1876.

To all whom it may concern i Be it known that 1, JAMES A. DURYEE, oNunda, in the county of Livingston and State of New York, have inventeda new and useful Improvement in Ghurn-Dashers, of which the followingis'a specification Figure l is a side view of my improved dasher. Fig. 2is a View of the same turned one-quarter around.

Similar letters of reference indicate corresponding parts. 1

The object of this invention is to furnish an improved churn dasherwhich shall be so constructed that it may be readily adjusted accordingto the amount of milk in the churn, which will bring the butter veryquickly, will gather the butter thoroughly, which shall be easilyoperated, and will work equally well when turned in either direction.

The invention consists in the combination of the sleeve, the cross-bar,the notched blades, the two cross-bars beveled in opposite directionsupon their lower sides, and the buttons with the main shaft and itscross-bar, as hereinafter fully described.

A is the main shaft of the dasher, to the lower end of which isattacheda cross-bar, B.

Upon the shaft A, above the milk, is formed a shoulder, a, upon whichrests the lower end of a tube or sleeve, 0. To the lower end of the tube0 is attached a crossbar, D, to the outer ends of which are attached theupper ends of two downwardly-projecting bars or blades, E, upon one edgeof each of which is formed a series of notches, e. The blades E passdown through slots in the crossbar F. To the center of the crossbar F ishalved a cross-bar, G, which is placed at right angles with the saidcross-bar F. The cross-bars F G, at their point of intersection, have ahole formed through them to receive the lower part of the shaft A, sothat the said bars can revolve upon the said shaft as a pivot. In

I the end parts of the cross-bar G are formed holes to receive the shortvertical tubes H, which receive air from the upper part of the churn,and carry it down into the milk. The

tubes H are placed farther from the shaft A than the blades E, so thatthe said blades and tubes may move in different paths. When thecross-bars F G are placed low down, the lower ends of the tubes H passthrough notches 1), formed in the upper sidesof the end parts of thecross-bar B. The cross-bars F G, when adjusted in proper position uponthe blades E, are secured in place by buttons I, pivoted to thecross-bar G in such positions that they may be'turned against the saidblades E. To the upper end of the tube 0 is attached, or upon it isformed, a bevel-gear wheel, J, and

to the upper end of the shaft A is detachably,

attached a bevel-gear wheel, K. The bevelgear wheels J K are placed atsuch a distance apart that their teeth may mesh into the teeth of agear-wheel interposed between them and attached to the crank-shaft, sothat the shaft A and its attachments, and the sleeve 0 and itsattachments, may be revolved in opposite directions. The lower sides ofthe cross-bars F Gare beveled in opposite directions upon their edges,so that the dasher may work equally well when turned in eitherdirection.

Having thus described my invention, I claim as new and desire to secureby Letters Patent The combination of the sleeve (3, the crossbar D, thenotched blades E, the cross-bars F G, beveled in opposite directionsupon their lower sides, and the buttons 1 with the shaft A and cross-barB, substantially as herein shown and described.
